To all 'whom it may concern:

Be it known that I, LOUIS WILPUTTE, a

subject ofthe Kingdom of Great Britain,

resi-ding in Joliet, in` the county of Will andV State of Illinois, haveinvented -a new and useful Improvement in LevelingeRams for Coke-Ovens,of which the following is a specification.

The object of this invention is to provide for lessening the loss of gasduring the operation of leveling the charge in coke ovens, and relatesto the means for accomplishing this result, consisting in general termsof a housing, or containing the leveling ram, to be joined in agas-tight manner to the opening in the ovenwhile such leveling opera--4tion is going on, so that t-he leveling ram operates in an inclosure ofwhich the oven 1s a part, thus greatly diminishing the escape of the gastoy the outer air and its consequent loss during `this time; and ityfurther consists in the novel devices and parts, and

` combinations of parts and devices, substany ing forms a part of thisspecification.

tiallyas hereinafter described, and shown in the accompanyingdrawing,which draw- In said drawing Figure l is a plan View of anapparatus embodying my invention; Fig. 2 is a side elevation of thesame; Fig. 3,-upon a somewhat larger scale,is a plan view of'a portionof the leveler ram indieating its construction more in detail; Fig. et

is an elevation of the same; and Fig. 5 is a cross section. thereof.

Like letters of reference indicate like parts wherever employed in theseveral figures.

The modern cokeovens, as iswell known to those skilled in the art, arebuilt in proximity to each other, a number side'by side, for convenienceof operation and other economiesl Along both faces of this multiplestructure are built tracks upon which to run cars or locomotives; at oneface` the cars into which the finished coke is discharged and quenched,and at the other face a track for the locomotive staging upon which ismountl ed the pushing ram for discharging the coke from the oven,and,sometimes also, the levelingram whichisrn'n into and reciprocated alongthe .uppenpart of the oven to level the freshlyzdeliveredgcoal which, asit is fed in .atseverall openingspintheroof, lies in heaps,

thusgto,-bringtthenppersurface: of said 'coal tok a comino';n horizontalplane to facilitate and-'equalize the coking. This leveling ram mayhowever, be mounted on a separate locothe better way', especially wherethe ovens are numerous. These locomotive ystagings are usually providedwith a cab toprotect the driver from the weather, and are moved frompointto point on the track bymeans of an electric motor controlled bythe driver from within said cab. Theyare also fitted With such motorsfor reciprocating the pushing ram and the leveling ram, one or both asthe case may be. In the facevof the oven at this side is the largeopening `through which the head of the pushing ramis admitted to passinto and V,through the oven chamber to push out the finished coke, andwhich opening during the coking is closed witha gas-tight or luted door.Above this large opening and near the upper part of the oven chamber isa' smaller opening or leveling hole to permit the entry into the ovenofthe leveling ram, closedk during the coking by a' gas-tight or luteddoor. This smaller door to admit the ram is necessarily opened after thecoal has been fed Ato the oven 'chamber and the coking begumftrndconsequently at a time when the gases are being freely and abundantlyevolved and standing injthejupper part of said oven so thatiwhenthe doorlis opened to admit the leveling ram and vall during the operation ofleveling 1 the.,` gas rushes continuously gout into theatmosphere and alarge amountnof it is., thus lost@ And as will be rememberedtheffutfilizatin of theseV gases as a, v'aluable-by-produjct of thecoking is, and has been the chief things soughtan modern-lcoking. 'Ioremedy this 'co'nditiorrg;.IyA have t devised my gas-tight', orpractically gas-tight,-hous ing .orl casing for 4the levelingf rami'llli'efffeal` tures of such a housing-@asdeveloped,`f-are the following:-It inclo's'es or ;hous"esth'e entire ram, in` a practicallyygasetightchar ber, at `least `-while the operationrof; leveling is beingperformed. It is-v capable `of ready application; tothe leveling holetomake'a reasonably tight-jbint-there; cIt embodies 3a pocket to receivethe dislodged coalgpulled. out of the, oven'by the act'ionfofihe ram-@orby its withdrawal. The structure' 3doesnot interfere with theoperationofy the: ,ov-en* or the closing andv opening of the doors thereof. These,are the principal advantages or re'- quirementsg-sot-hers of lesser.note will appear as the description lis lhereinafter further given.It?l xvliiljlwbe understood, b v those skilled in the art, that themaking of an ab- Solutely gas-tight removable chamber to contain theleveling ram' and to beapplied to and removed from the leveling hole 4ofthe.

Upon the locomotive stagingis erected the frame-work 20, for supporting l the leveling ram and`itsl housing.'

"Ihele'velingv ramj is shown at 21. f' It is` made of two long sidepieces 211, 212, conf "nected together bythe zig-za bracing strip 21,3riveted at alternate ang es to one and to the other of the side pieces,as will be better understood by reference to the detail Figs. 3, 4 and 5pf thel drawing. The side pieces' 211, 212,' at'theirl forward ends areshowntapering/from below upward 'so that the portion that y.first entersthe oven shall be Vthe smaller. And, below #the zig-zag brace 213ithesaid ram is. provided with a seriesfffross-bai's 214, each having afriction l'sleeve' Aor roller 215,the series forming a rack' to, beengaged by the driving pinion 2.2,'` constituting 4a means by which saidram may be .moved'in and out of thefoven and rec1procated while withinthe oven chamber. Th'p'inion 22 is driven in either direction by theelectric motor 23, through gears, and controlled froxnwithin the cab.That the driver may? knowwhen to reversethe mechanism so that. theleveling ram shall not be run in or drawiimt too far, an indicatordevice to be ,observed,"`-`may vbe employed, such for ex ample as thebell 221 to be'struck and sound "ed in both `directions byx theprojections 222, 223, which may also preferably be so placed as tobeseen by the eye of the driver to indicate to him the position of theram in case the bell does not sound or is .removed for any cause. Thatthe ram may move freely, and

p withoutbi'riding, friction rollers 224 are provided for supporting thesame above and below.

The housing or extensible chamberfor inl closing the leveling ram isshown at 24. .It is supported preferably labove the cab on `riding uponthe surface ofthe ram, and

when the ram is moved forward toward the oven far enough to enterv thesame yit gets out from under the door which thus closes of its ownweight and Amakes the housing or chamber at' this end practically lgastight. To-prevent-wear and facilitate this action, the door 25isprovided with friction roller 251 that rides on the surface of the ramduring the movement of the latter. In front of the cab and nearer thefront end ofthe housing it will be seen that the housing or chamber isprovided with pocket. 26, having an inclined floor 261 near the lowerend ofj which is. a door 262. AI portion 263 of the ioor at the front isinclined in the other direction. The purpose of. this pocket is to catchwhatever coal may be incidentally and un'- intentionally pulled out ofvthe oven",l and into the housing by theI action of the level- 7o lv4the framework of the locomotive staging,

`ing ram, either in its leveling reciprocation withinthe oven or'in itswithdrawal therefrom, and to retain said incidental coal until after-theovens have been leveled, when itmay convenientlybe discharged from saidpocket by the opening of the door 262 ,above referred to. The front endof thisfhousing is so contrived that it may be moved or exaccommodateits application and removal from the oven .and to permit the locomotivelthe-:front end of the stationary part and. the

rear end of the movablepart of lthe housing,

Itended to a certain amount, suiicient to both open, are made inclinedwith opposite inclines 244, 245, and that a wedge-shaped intermediatesection 246'is movably interposed betwcenthese two inclined ends. Theresult is that when the wedge-shaped intermediate section is lifted outof place. the extensible .part of the housing may be moved freely .abackand farai; anaehat when the housing is fully extendedv the Wedgeshapedintermediate sectionfmay be lowered intohplace andgjivedginghomer apractically gas tight continuation of the housing passage is produced.This construction is such 'as will be understood 'by those skilled inthe art that the operation is not materially interfered With by thedeposit of gastar which takes place in appliances used in this relation.To extend and Withdraw the movable part of the housing racks 247 andpinions 248 are Provided, the latter operated by a crank 249 Within thecab connected bv pulley and chain with the pinions 248. Anch to raiseand lower the Wedge-shaped intermediate section a chain 2461 is carriedfrom the'pulleys 2462, 2463, to a crank 2464 in the cab, a counterWeightA 2465- on said chain tendingto counterbalance the Weight of thesaid intermediate section. vand thus render the operation of lraisingand lowering thev framing around Asaid levelinghole and makes apractically close joint; then by the aid of -the other crank he lowersinto place the wedge shaped intermediate section thus making acontinuous close housing from the oven 4back tothe rear end 'Where 'theinclined door still' remains open; but immediately and as soon4 as vthejoining is thus complete the driver starts the leveling ram motor togoing which rapidly moves the forward end of i said ram into the ovenand runs .the rear end Within 'the housing permitting the inclinedlvalve door to close said rear end of the housing. lVhenl the front endof the ram has gone in far enough-the bell rings and e. driver thenreverses the-motor and runs it back and forth in the 'oven with areciprocating stroke of about five' feet, more or less, until the coalis perfectly leveled, the zig-zag braces serving to rake the coal anddistribute'it evenly in the oven top into proper shape for even andregular coking. The leveling having been thus accomplished, the ram isquickly withdrawn and run back lto its limit, the intermediate sectionlifted,

andthe extensible'section Withdrawn, leav ing theleveling hole clear sothat the asslstvant on the oven plat-form may close the same. Such coalas may be Withdrawn aceidentally by the action ofthe ram falls into theretaining pocket and by its inclined bot-- torn is discharged ataconvenient time and Although some glas operation. itl will be seen thatby the .use of l .as
